Patented Apr. 17, 1951 UNITED STATES ATEN T OFFICE METHOD OF ATTACHINGDECORATIVE PANELS TO WALL SURFACES Samuel D. Bosco, Wood River, Ill.

2 Claims. (01. 154 141) This invention relates in general to the methodof attaching decorative panels to wall surfaces.

The primary object of this invention is to provide a method of attachingdecorative panels in most secure and perman nt manner to surfaces ofeither interior or exterior Walls.

A further object of this invention is to provide a method of attachingdecorative panels to Wall surfaces which is economically performed andrequires no preliminary treatment of the Wall surface.

In present day operations, it is necessary to treat wall surfaces onwhich decorative panels are to be mounted in some preparatory fashion,Whether it be to clean, smooth, or remove a superficial finish. Inutilizing the method herein disclosed, the necessity of such preliminarysteps is obviated. The surface, regardless of its condition as tocleanliness or finish, is sized with a solution of equal parts by weightof Epsom salts (MgSO4-7I-I2O) and water. After allowing the Epsom saltssolution to dry, a coating consisting of equal parts by weight of caseinglue and water, is applied and permitted to dry. A second and finalcoating consisting of two parts by Weight of casein glue and one part byweight of water is then applied to the wall and a coating of the samematerial is similarly applied to the rear or wall-abutting face of thedecorative panel. While this last coating is still moist, the decorativepanel is pressed in place on the wall.

Pressure is exerted to maintain the panel against the wall until themoist adhesive has set, either by manually applied force or by proppinga batter or jack thereagainst. When the adhesive has set, the externallyapplied pressure may be removed and the panel left to dry in place,whereupon the panel will be found to be attached to the wall in apermanent, lasting manner.

The present method is best employed in mounting decorative panels up toapproximately forty square feet in area and eighty pounds in weight. Apressure of about twenty-five pounds produced by automatic jacks, orother convenient means, exerted for about twelve hours, is adequate formaintaining panels of the above maximum size and weight in position forsetting.

It is to be particularly noted that the nature of the wall surfacemounting the panel is immaterial, in the present method, that is, it maybe an exterior or interior wall, and composed of brick, stone, concrete,or tile. It should be understood that in the present context the wordWall includes floors and ceilings, as the case may be.

It should be understood that changes in the methods, compositions,percentages, and combinations above set forth may be made withoutdeparting from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. The method of attaching decorative panels to walls composed of brick,stone, concrete, tile, consisting of applying to said walls a sizing ofmagnesium sulfate solution, when the sizing is dry applying an initiallayer of casein glue solution, when such initial layer is dry applying alayer of casein glue solution of thicker consistency, said thickercasein glue solution being applied to said decorative panel, andmaintaining said decorative panel against said wall under positivepressure until the glue has set.

2. The method of attaching decorative panels to Walls composed of brick,stone, concrete, tile, consisting of applying to said walls a sizing ofa solution comprised of equal parts by weight of magnesium sulfate andwater, when the sizing is dry applying an initial layer of glue solutioncomprising equal parts by weight of water and casein glue, when suchinitial layer is dry applying a layer of casein glue solution of thickerconsistency, said thicker casein glue solution being also applied tosaid decorative panel and maintaining said decorative panel against saidwall under positive pressure until the glue has set.
